Takeoff views of the Himalayas are exceptional and unique to this route—the dramatic mountain scenery is worth prioritizing. Landing views at Incheon are good from the right, but the Himalayan departure from the left is the more memorable segment of this flight.

Flight Path
Kathmandu to Seoul is 2,465 miles (3,966 km), a flight of about 5 hours 15 minutes.
The flight path crosses the Tibetan Plateau at cruise altitude (around 35,000 feet). You'll pass over the eastern edge of the Tibetan Plateau with its characteristic brown, barren terrain and sparse settlements. The Yangtze River's upper reaches may be visible as a thin line in good visibility. As you approach China's eastern border, you'll transition over increasingly green, cultivated terrain in Sichuan and Hubei provinces. The Yellow River valley becomes visible in the final approach to Korean airspace. At cruise altitude, individual landmarks are difficult to distinguish, but the broad geographic transition from high plateau to lowland river valleys is apparent.
